Filed: 1988-10-13
Abstract: PURPOSE:To decrease the gas trouble cases by preparing a gas leak sensor and deciding the cut-off of the gas supply after confirming a gas leak via an expert based on the information received from the gas leak sensor and the change of the value of a gas meter. CONSTITUTION:A gas sensor 1 is connected to an automatic informing device 4 and informs the abnormality if detected to a center 5 via the device 4 and a telephone line 6. Thus a gas expert of the center 5 calls a telephone 8 of a terminal home that delivered the information and confirms the information via the resident there. In case the leak continues for a designated time, the information is given again to the center 5. In this case, the device 4 checks whether the value of a gas meter 7 is changed or not. If the change is confirmed, the telephone 8 is called again. In case the resident is absent or the due treatment is impossible, a controller 2 is activated to start a cut-off valve 3. thus the supply of gas is stopped. In such a way, a gas leak is decided by an expert based on the change of the value of the meter 7. Thus the gas trouble cases like the wrong cut-off of the gas supply, etc., due to the malfunction of the sensor 1 can be decreased.

IPC: G11B5/31
Filed: 1988-10-14
Abstract: PURPOSE:To prevent sticking of a plating film to the pole part of a magnetic film by coating the peripheral of the pole part of the magnetic film with a resist, then forming a conductor coil pattern consisting of the plating film on an underlying conductor film at the time of forming a conductor coil film. CONSTITUTION:The periphery of the pole part 21 of the magnetic film 2 is coated with the resist 12 prior to execution of a pattern plating treatment. The Cu plating film 51B is thereafter stuck to the part 62B where the resist film 62A is removed. The Cu plating film 51B does not, therefore, stick to the pole part 21 of the magnetic film 2 in the pattern plating stage. The resist film 62A is then peeled and, therefore, the underlying conductor film 51A exist ing under the peeled resist film 62A is removed by ion milling in the state of sticking the resist 12 and is thereby patterned according to the conductor coil pattern consisting of the Cu plating film 51B. The resist 12 is hardly peelable if the impressed power of the ion milling is too large and, therefore, the impressed power of the ion milling is adjusted to the range where the resist 12 can be peeled.
